Interspecies Comparison of Chlorinated Contaminant Concentrations and Profiles in Wild Terrestrial Mammals from Northwest Poland

The aim of this study was to determine residual polychlorinated biphenyls (PCBs) and organochlorine pesticides in the adipose tissue of wild terrestrial mammals coming from the same area in northwest Poland and to compare the organochlorine content and profile between species. The study was performed on five mammalian species, including omnivores (badger, wild boar, raccoon dog) and herbivores (roe deer, red deer). The obtained results show that the levels of residues of most of the analyzed compounds were greater in omnivorous mammals than herbivorous mammals. We found differences in the pattern of accumulation of organochlorines. In the raccoon dog organochlorines accumulated in the following descending order: DDTs > PCBs > HCHs > endrin > dieldrin; in the badger, wild boar, and roe deer, the order was as follows: DDTs > HCHs > PCBs > endrin > dieldrin; and in red deer, the order was as follows: HCHs > DDTs > PCBs > endrin > dieldrin. PCB 153 was dominant in herbivores and in the wild boar, whereas in the raccoon dog it was lower than PCB 138 and in badger lower than PCB 180. These differences in the tested species may reflect differences in metabolic capacity and/or feeding habits and an uneven distribution of organochlorines in the area where the animals lived. Maximum residue levels (MRLs) were exceeded in single samples from animals whose meat and fat can be consumed by humans. The greatest number of cases where MRLs were exceeded was observed in the adipose tissue of the badger (HCHs, DDTs, endrin, non-dioxin-like PCBs) and the fewest in the adipose tissue of roe deer (only lindane).     

Ludowe zabobony i przesądy czy racjonalne metody żywienia noworodków i niemowląt w końcu XVIII i w XIX stuleciu?

The article presents opinions that prevailed among the country population, as well as physician reports regarding feeding of newborns and infants on Polish lands. This information is from the turn of the 18^th and 19^th centuries. Information regarding various ways of feeding the newborns can be found in historical monographs and articles. Breast feeding by mother or a wet nurse was essential to the child's healthy development. However, for numerous reasons human milk was being substituted by animal milk, especially cow milk, horse milk and donkey milk. The folk methods of substituting mother's milk were often surprising and harmful for the baby. Moreover, according to epidemiological research of those times, medical recommendations regarding the use of artificial food had a significant influence on high mortality among babies.     

Persistent ductus arteriosus in a 72-year-old woman with paroxysmal atrial fibrillation and depression syndrome: a therapeutic and diagnostic problem

Treating the elderly is often problematic, especially when congenital heart disease is diagnosed. The aim of this study is to present the case of a 72-year old woman with depression syndrome, paroxysmal atrial fibrillation and past cerebral stroke, in whom persistent ductus arteriosus Botalli was diagnosed. Due to exacerbation of the depressive syndrome, she did not give her consent to further diagnostics, possible interventional procedures and treatment with oral anticoagulants. After intermission of the therapy she was treated with dabigatran. The patient is still undergoing outpatient treatment and so far, no cerebrovascular episodes have been recorded.     

New diagnostic criteria for alcohol use disorders and novel treatment approaches – 2014 update

The study is aimed at presenting new diagnostic and therapeutic proposals for patients with alcohol use disorders. The revised ICD-11 which is currently being updated is coming closer to American standards in disease classification. The latest update of the American DSM-5 has been a notable step forward as it integrates alcohol abuse and alcohol dependence into a single disorder called alcohol use disorder. Recent developments in research into diagnostic tools have brought changes in the approach to therapy. According to most international guidelines, the form of treatment should be customised to the individual patient, with consideration given to his/her mental and physical condition, personality and natural setting. A significant change is the recommendation of a harm reduction strategy as a useful alternative to total abstinence in alcohol dependence treatment for some patients.     

Natural products against cancer angiogenesis

The process of angiogenesis is quite well-known nowadays. Some medicines and extracts affecting this process are already used routinely in supporting the conventional treatment of many diseases that are considered angiogenic such as cancer. However, we must be aware that the area of currently used drugs of this type is much narrower than the theoretical possibilities existing in therapeutic angiogenesis. Plant substances are a large and diverse group of compounds that are found naturally in fruits, vegetables, spices, and medicinal plants. They also have different anticancer properties. The aim of this literature review article is to present the current state of knowledge concerning the molecular targets of tumor angiogenesis and the active substances (polyphenols, alkaloids, phytohormones, carbohydrates, and terpenes) derived from natural sources, whose activity against cancer angiogenesis has been confirmed.
